True - but some people *really* need that help - especially the people who
don't even understand that there *are* two separate concepts - which, per
Dave's report, are thick on the ground in legal-land.

I also plead guilty (as I expect most here do - except maybe Alex :-). But I
think the sin is more fundamental - we should never have started using it in
the second way at all. Anyway, too late now...

I disagree.

As an example, it may be that when *I* use the term "address", I'm not
confused in my thinking, but I can guarantee that *some* of the people in the
IETF who use this term *are* confused - although I do think that the number
has declined very considerably over the years, and the situation is now quite
good. But this is of course many years after a concerted effort to make
people think separately about location and identity got started...

So I think separate words will help, and I think we should make a concerted,
long-term effort to straighten this out.
